Answer:
12/12=20/20
Step-by-step explanation:
if the original question deals with fractions, then 12 over 12 is the same as 20 over 20 because they both reduce to 1
Answer:
see below
Step-by-step explanation:
The sum of the interior angles is 180
<1 + <2 + <4 = 180
<1 + 31+ <4 = 180
<1 + <4 = 180-31
<1 + <4 = 149
<2 + <3 = 180 because it forms a straight line
31 + <3 = 180
<3 = 180-31
<3 = 149
Setting theses equal (since they are both equal to 149)
<1 + <4 = <3
The exterior angle is equal to the sum of the opposite interior angles
Answer:
One solution is to find x and y by doing the following:
Step-by-step explanation:
Let's solve for x.
3x+2y=4
Step 1: Add -2y to both sides.
3x+2y+−2y=4+−2y
3x=−2y+4
Step 2: Divide both sides by 3.
x=-2/3y+4/3
Lets solve for y.
3x+2y=4
Step 1: Add -3x to both sides.
3x+2y+−3x=4+−3x
2y=−3x+4
Step 2: Divide both sides by 2.
y= -3/2x+2
Answer:
x = 12√1.5
Step-by-step explanation:
Law of sines.
12/sin45 = x/sin60
x = 12(½√3) / (½√2)
x = 12√3/√2
x = 12√1.5
Answer:
the answer is 81
Step-by-step explanation:
1. find 75
2. add 75 + 24
3. subtract from 180 to find x
